“…The two species are often found sympatrically, but L. praecox tends to be observed in relatively moist sites, such as the lower slope and stream banks at our study site (Isogimi et al 2014). Most individuals of the two species form clumps of a few large and many smaller ramets sprouting from the ground (i.e., genets) (Matsushita et al 2010;Isogimi et al 2014). In an oldgrowth forest, the size of the largest ramet within a genet (hereafter, the main ramet) of L. triloba is larger than that of L. praecox in both genders.…”

“…In an oldgrowth forest, the size of the largest ramet within a genet (hereafter, the main ramet) of L. triloba is larger than that of L. praecox in both genders. The total number of ramets per genet is approximately the same between species, and male genets have more ramets than females in both species (Isogimi et al 2014). In L. triloba, ramet growth and survival rates do not differ between genders (Matsushita and Tomaru 2012), whereas flowering traits (inflorescence number per ramet or genet, and number of flowering ramets per genet) are larger in males than females ).…”

The architecture of trees is a crucial determinant of their performance through light capture and mechanical stability. Comparison of architectural traits between closely related dioecious species is predicted to reveal both inter-specific and sexual differences. The former may reflect life-history characteristics such as microhabitat preferences, and the latter may reflect costs of reproductive allocation. We measured branching structure, leaf traits, wood density, and biomass of each vegetative component in the dioecious shrubs Lindera praecox and Lindera triloba to explore architectural differences according to species and gender. L. triloba was less branched but had a greater total leaf mass per shoot having larger and heavier leaves than L. praecox; most of these traits did not differ by gender. Allometric relationships between height and branch biomass corroborated our results of branching structure. The allometric relationships between tree size and leaf biomass demonstrated that in larger size classes females of both species had greater leaf biomass than males. Females of both species also showed lower tree height than males. This study suggests that tree architecture is influenced by both life-history strategy and resourceallocation pattern. Branching structure and branch biomass showed inter-specific differences, with the highly branched L. praecox apparently more shade tolerant than L. triloba; its tolerance is likely adaptive in its preferred microhabitat where is often lit poorly. Sexual differences in leaf biomass and tree height growth may reflect higher reproductive costs incurred by females.

AbstractClonal plants are frequently affected by process of disturbance as fragmentation. The capacity of these fragments to survive and grow after disturbance has important implications for the expansion of clonal plants, and could have special consequences for the colonization of new environments by invasive clonal species. Stolon internodes of clonal plants represent important reserve organs. These storage structures can play a crucial role in the survival and re-growth of clonal plants after an event of disturbance. In this study we simulated physical disturbance by fragmentation of clones of the stoloniferous invader Carpobrotus edulis into ramets with short and long stolon lengths, and a subsequent event of seawater submergence and de-submergence. Ramets with long stolons showed a significantly higher total biomass than ramets with short stolons, supporting the idea that stolon length is related with the amount of reserves stored and with the benefit reported in terms of growth. Our results showed that the benefit of having long stolons was also important for clonal fragments that suffered a process of seawater submergence. Our study suggests that the use of stolon as a source of resources can represent a suitable mechanism for colonization of coastal sand dunes by the aggressive invader C. edulis.3
